TV tonight: 'CMT Music Awards,' more

USA TODAY - What's worth watching, and what might not be, in prime time on Wednesday.

CMT Music Awards | CMT, 8 ET/PT

Are country stars even able to keep track of the various music awards they're nominated for, or the related shows they perform on? My bet is you could host an awards show in your backyard and some of them would show up by mistake. That said, we have entered TV's slow stretch and tonight's CMT Music Awards does offer a chance to hear some of your favorite performers -- a list that's scheduled to include George Strait, Taylor Swift, Little Big Town and, naturally, Carrie Underwood, as it's apparently illegal to do one of these shows without Carrie Underwood.

Supernatural | CW, 9 ET/PT

Rule No. 1 when fighting demons and searching for mysterious, magical objects: Don't bring along your mother. You'll see why that's a rule tonight on this Supernatural repeat, as Sam and Dean's quest for the tablet and battle with Crowley (Mark Sheppard) gets hijacked by an uninvited guest, Kevin's mother (Lauren Tom).

How to Live with Your Parents for the Rest of Your Life | ABC, 9:30 ET/PT

Speaking of rules, one of the old guidelines of scriptwriting used to be "write what you know" -- which is what creator Claudia Lonow did with this loosely autobiographical sitcom about a divorced woman moving home with her young child in tow. It didn't work, in part, because the story -- true or not -- has already been used in bits and pieces by other recent sitcoms. But there's a good cast at work here, led by Sarah Chalke and Elizabeth Perkins, and their work, if not original, at least isn't a repeat.
